<p>[QUOTE=&quot;borgovan, post: 804984, member: 13016&quot;]It was just toned; that&#039;s all.</p><p>&nbsp;</p><p>What is toning? Toning is the visual indication our eyes receive when the surface layers of a metal have undergone oxidation. In this case, the nickel/copper alloy of the 5-cent-piece has reacted with sulfur compounds in the atmosphere. Certain molecules have reacted with the surface of the metal, thereby allowing various different colors of light to be absorbed and/or reflected. We then see the reflected colors; this is what is called toning.</p><p>&nbsp;</p><p>It is common and is a natural process, although certainly it can be artificially accelerated. Beautifully toned coins generally carry a premium. The type of toning your coins have displayed are common, and would carry little, if any, premium. </p><p>&nbsp;</p><p>I would classify this as natural toning.[/QUOTE]</p><p><br /></p>
